[0026] Please refer to Figures 1-5 An improved dredging device for pipeline for water conservancy projects, comprising an installation box 1, a dredging mechanism 2 extending to the outside of the installation box 1 is fixedly connected in the inside of the installation box 1, and a positioning mechanism 3 is fixedly connected to the left side of the installation box 1.

[0027] The dredging mechanism 2 comprises an electric push rod 21, the output end of the electric push rod 21 is fixedly connected with an adjusting rod 22, the right side of the adjusting rod 22 is fixedly connected with a mounting block 23, the outer side of the mounting block 23 is fixedly connected with a fixed cylinder 24, the inside of the fixed cylinder 24 is slidably connected with a sliding block 25, the sliding block 25 and the inner bottom wall of the fixed cylinder 24 are fixedly connected with a spring 26, the other side of the sliding block 25 is fixedly connected with a connecting rod 27, one side of the connecting rod 27 is fixedly connected with a cleaning brush 28, and one side of the connecting rod 27 is fixedly connected with a scraper 29.

[0028] The positioning mechanism 3 comprises a mounting frame 31, the right side of the mounting frame 31 is fixedly connected with a first clamping block 32, the inside of the mounting frame 31 is fixedly connected with a double-shaft servo motor 33, the two output shafts of the double-shaft servo motor 33 are fixedly connected with threaded rods 34, the outer sides of the threaded rods 34 are threadedly connected with threaded blocks 35, and the right sides of the threaded blocks 35 are fixedly connected with second clamping blocks 36.

[0029] Specifically, the inner wall left side of the mounting box 1 is fixedly connected with a speed reducer 11, the output shaft of the speed reducer 11 is fixedly connected with a rotating disc 12, and the outer side of the rotating disc 12 is fixedly connected with a positioning ring 13.

[0030] Through the above technical scheme, starting the speed reducer 11 can drive the rotating disc 12 and the positioning ring 13 to slowly rotate, thereby realizing the slow rotation of the cleaning brush 28 and the scraper 29, and facilitating the cleaning of the silt on the inner wall of the water conservancy project pipeline.

[0031] Specifically, the electric push rod 21 is fixedly connected to the right side of the rotating disc 12, and the inner wall of the mounting box 1 is provided with a positioning groove matched with the positioning ring 13.

[0032] Through the above technical scheme, the positioning groove limits the rotating track of the rotating disc 12, thereby ensuring that the cleaning brush 28 and the scraper 29 do not deviate in position on the inner wall of the pipeline.

[0033] Specifically, the right side of the adjusting rod 22 penetrates and extends to the right side of the mounting box 1, the mounting block 23 is designed as a triangular prism, and the fixed cylinders 24 are respectively installed on the three sides of the mounting block 23.

[0034] Through the above technical scheme, the surface of the mounting block 23 designed as a triangular prism can be provided with multiple fixed cylinders 24, thereby multiple cleaning brushes 28 and scrapers 29 can be installed, and the efficiency of dredging the inside of the water conservancy project pipeline is improved.

[0035] Specifically, the connecting rod 27 is fixedly connected with a connecting plate on the side away from the sliding block 25, the cleaning brush 28 and the scraper 29 are fixedly connected to the connecting plate, and the spring 26 is always in a compressed state.

[0036] Through the technical scheme, under the action of the connecting plate, the scraper 29 and the cleaning brush 28 are installed together, the sludge is hung by the scraper 29 first, and then is cleaned by the cleaning brush 28. Since the spring 26 is always in a compressed state, the spring 26 always has an outward force on the sliding block 25. Under the transmission of the connecting rod 27, the cleaning brush 28 and the scraper 29 are always pressed against the inner wall of the pipeline, and the effect of cleaning the inner wall of the pipeline is improved.

[0037] Specifically, the mounting frame 31 is fixedly connected to the left side of the mounting box 1, the first clamping blocks 32 are two in number and symmetrically distributed above and below, and the second clamping blocks 36 are two in number and symmetrically distributed.

[0038] Through the technical scheme, the two first clamping blocks 32 are placed in close contact with the outer wall of the water conservancy pipeline, the preliminary fixing of the entire dredging device is realized, and then the spacing of the two second clamping blocks 36 is adjusted until the inner wall of the pipeline is in close contact, so that the further fixing of the entire dredging device is realized.

[0039] Specifically, each of the two threaded rods 34 is provided with a threaded section, the two threaded sections are of the same length and opposite directions, and the front and rear sides of the threaded block 35 are slidably connected to the inner wall of the mounting frame 31.

[0040] Through the technical scheme, since the two threaded sections are of the same length and opposite directions, the two second clamping blocks 36 can move the same distance relative to or away from each other, so as to facilitate the fixing of the entire dredging device. Since the threaded block 35 is slidably connected to the inner wall of the mounting frame 31, the threaded block 35 and the second clamping block 36 will not rotate together with the threaded rod 34.

[0041] In use, first, the double-shaft servo motor 33 is started in forward rotation, and under the action of the two threaded blocks 35, the two second clamping blocks 36 are moved relative to each other to the closest distance, the mounting box 1 is inserted into the water conservancy pipeline, and the opposite sides of the two first clamping blocks 32 are in close contact with the outer wall of the pipeline. Then, the double-shaft servo motor 33 is started in reverse rotation, so that the two second clamping blocks 36 move away from each other until the opposite sides of the two second clamping blocks 36 are in close contact with the inner wall of the pipeline, so that the entire dredging device is fixed on the pipeline. Then, the electric push rod 21 is started to move the adjusting rod 22 outward of the mounting box 1, so as to move the cleaning brush 28 and the scraper 29 into the water conservancy pipeline. Since the spring 26 is always in a compressed state, the spring 26 always has a spring force on the sliding block 25. Under the connection of the connecting rod 27, the cleaning brush 28 and the scraper 29 are always pressed against the inner wall surface of the pipeline. The sludge on the inner wall of the water conservancy pipeline is cleaned by first scraping the sludge on the inner wall of the pipeline by the scraper 29 and then brushing the sludge by the cleaning brush 28. After the cleaning, the entire device is disassembled, and then the sludge is flushed out by spraying water into the pipeline.
